The combination of several separation methods with the Fritz Haber Institute free electron laser has allowed to measure infrared spectra of size selected peptide-ion aggregates in the gas phase. The spectra reveal information on the peptides’ folding states, varying between helical and β-sheet. In the future, this approach of determining folding in peptide and protein aggregates can, potentially, contribute to the better understanding of protein misfolding, aggregation and the hereby caused diseases.
